What Is Type 2 Diabetes?
Type 2 diabetes is a chronic condition in which the body either doesn't produce enough insulin or doesn't use insulin effectively. Insulin is a hormone that helps regulate blood sugar (glucose) levels. When glucose builds up in the bloodstream instead of being used for energy, it can cause a wide range of health complications over time.
Unlike Type 1 diabetes, which is an autoimmune condition, Type 2 diabetes is strongly linked to lifestyle factors and can often be prevented or delayed with the right changes.
Early Warning Signs
Type 2 diabetes can develop gradually, and many people have it for years without realising. Common early warning signs include:
- Increased thirst and frequent urination
- Unexplained fatigue or low energy
- Blurred vision
- Slow-healing wounds or cuts
- Tingling or numbness in the hands and feet
- Frequent infections (particularly skin, gum, or bladder infections)
- Unexpected weight loss
If you're experiencing any of these symptoms, it's important to see your doctor for a blood glucose test as soon as possible.
Who Is at Risk?
Several factors increase your likelihood of developing Type 2 diabetes:
- Age: Risk increases significantly after age 45
- Family history: A parent or sibling with diabetes raises your risk
- Being overweight: Especially excess weight around the abdomen
- Physical inactivity: Sedentary lifestyle affects insulin sensitivity
- High blood pressure or abnormal cholesterol levels
- History of gestational diabetes
- Prediabetes: Blood sugar is higher than normal but not yet diabetic range
How to Reduce Your Risk
Research consistently shows that lifestyle changes are among the most effective tools for preventing Type 2 diabetes. Here's what you can do:
- Achieve and maintain a healthy weight — Even a modest reduction in body weight can meaningfully improve insulin sensitivity.
- Get moving — Aim for at least 30 minutes of moderate exercise most days. Walking, cycling, and swimming all count.
- Choose whole foods — Prioritise vegetables, legumes, whole grains, and lean proteins over processed or high-sugar foods.
- Limit sugary beverages — Soft drinks, juices, and energy drinks spike blood sugar rapidly.
- Reduce refined carbohydrates — White bread, white rice, and pastries are quickly converted to sugar.
- Don't skip regular screenings — A simple fasting blood glucose or HbA1c test can detect prediabetes early.
Prediabetes: An Important Window
Prediabetes is a condition where blood sugar levels are elevated but not yet high enough for a Type 2 diagnosis. It is a critical warning signal — and an opportunity. Studies show that targeted lifestyle changes during this stage can prevent or significantly delay the onset of Type 2 diabetes. If you've been told your blood sugar is "borderline," take it seriously and speak with your doctor about a management plan.
